Most cyberattacks start with an email. That's why Varonis Systems is expanding its Microsoft 365 offering and improving the protection of the cloud-based email service Microsoft Exchange Online.
It is estimated that 91 percent of cyberattacks begin via email. Mailboxes contain a lot of sensitive data that can easily fall into the wrong hands without the right protection.
AI increases the threat
Despite being the source of some of the largest data breaches, email remains a blind spot for many companies. Artificial intelligence further exacerbates the threat situation as Microsoft 365 Copilot and other generative AI tools use user permissions to scan emails. Therefore, companies need to reduce email access using a least-privilege approach.
Support through automated email security
Varonis helps security teams proactively reduce the email attack surface, stop data exfiltration, and mitigate generative AI risks with accurate and automated email security, enabling customers to:
- Identify mailboxes that are accessible to guest and external users and others.
- Limit and monitor access to sensitive mailboxes and calendars.
- Detect and report data breaches or improper handling of data.
- Verify the effectiveness of data loss protection policies and quickly remediate gaps.
- Conduct security investigations with a detailed audit trail of all email activity (sending, receiving, deleting, etc.).
- Automatically respond to abnormal email activity that could indicate data exfiltration and other email-based attacks or abuse.
Reduce email-based cyber incidents
“An effective Data Security Posture Management (DSPM) strategy must also include email,” explains Brian Vecci, Field CTO at Varonis. “Varonis scans millions of emails, assigns mailbox permissions and monitors activity. This allows our customers to dramatically reduce the likelihood of an email-based data incident using the same cloud-native platform they use to secure data across SaaS, IaaS and hybrid clouds.”

About Varonis Since its founding in 2005, Varonis has taken a different approach than most IT security providers by placing company data stored both locally and in the cloud at the center of its security strategy: sensitive files and e-mails, confidential customer, patient and Employee data, financial data, strategy and product plans and other intellectual property. The Varonis data security platform (DSP) detects insider threats and cyber attacks through the analysis of data, account activities, telemetry and user behavior, prevents or limits data security breaches by locking sensitive, regulated and outdated data and maintains a secure state of the systems through efficient automation .,
